Answer:
<h2>a. V = 420 cm³</h2><h2>b. V = 444 in³</h2><h2>c. V = 108 cm³</h2><h2>d. V = 324 m³</h2>
Step-by-step explanation:
We have the rectangular prisms.
The formula of a volume of a rectangular prism is:

l - length
w - width
h - height
==========================================
Look at the picture.
a.
Two congruent rectangular prisms 14cm × 3cm × 5cm.

b.
One rectangular prism 15in × 4in × 6in and next 7in × 4in × 3in:

c.
One rectangular prism 10cm × 3cm × 2cm and next 4cm × 3cm × 4cm:

d.
One rectangular prism 10m × 3m × 6m and next 8m × 3m × 6m:

Answer:
Ratios are 2:3:5 given. So, 2*X+3*X+5*x=180° — sum of three angles of a triangle. So, X=18°. Hence angles are 36° , 54° and 90°

Answer:
1.56
Step-by-step explanation:
156 divided by 100
In this question, you are given the width( 20 miles), the length(28 miles) and the height( 1 inch). You are asked to count the rain water volume which was going with formula length x width x height. But the unit asked is ft, so you need to convert them all. The calculation would be:
Water volume= length x width x height
Water volume= 20 miles x 5280ft/miles x 28 miles x 5280ft/miles x 1inch x 1ft/12inch
Water volume = 1300992000 cubic ft.
Answer:175
